A reaction vessel inside a calorimeter contains 150 g of water at 19C. A reaction takes place in this chamber, after the reaction is complete the temperature of water is 29C. How many Joules were released/abosrbed during this reaction?

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.
